GUARD FOR ROLLERS.

Specification of Letters Patent.

Patented July 13, 1915.

Application filed August 10, 1914. Serial No. 856,138.

To all whom it may concern:

Be it known that I, MICHAEL BISHOP, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Guard for Rollers, of which the following is a specification.

The object of my invention is to provide a guard for rollers and the like, of simple, durable, and inexpensive construction.

A further object is to provide such a guard, which can be readily and easlly mounted and adjusted on the form which supports the rollers, and which is provided with adjustable members adapted to recelve between them material passing through the rollers, which adjustable members serve as a guard to prevent the workmen from catching their clothes or fingers in the rollers, which members may be adjusted to provide for the passage of materials of diiferent thicknesses and are adapted to serve as guides for such material.

My invention consists in certain details in the construction, combination and arrangement of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim and illustrated in the accompanying drawings, in which:

Figure 1 shows the front elevation of a set of rollers mounted in a frame and equipped with a guard embodying my 1n- 'vention. Fig. 2 shows a vertical transverse sectional view, taken on the line 22 of Fig. 1.

In the accompanying drawings I have employed a reference numeral 10 to indicate a frame on which are suitably mounted the rollers 11. One of the rollers is provided with an adjusting device 12, which forms no part of my present invention. The frame 10 includes the upright members 13 and 14, at the ends of the rollers.

My improved guard for rollers comprises two supporting brackets, each of which has a flat portion 15, that is to be secured to a suitable part of the frame, as, for instance, the upright members 13 or 14, by means of screws 16 or other suitable devices. The brackets are formed with portions 17 curved outwardly away from the frame, and with portions 18 curved inwardly toward the horizontal line between two rollers, as shown in Fig. 2. The portions of each of the brackets on each side of the inwardly curved portion 18,.which I have indicated generally by the reference characters A and B, are curved to conform somewhat in outline to the curvature of the rollers 11.

Two transverse guard members 19 and 20 have their ends secured to the respective portions B and A of the two brackets on the services thereof adjacent to the rollers. The members 19 and 20 connect the two brackets, and where the rollers are arranged horizontally said members 19 and 20 are arranged horizontally.

The members 19 and 20 are curved inwardly toward the rollers and away from the brackets at their adjacent edges, as shown in Fig. 2, and are designed to be spaced apart a suflicient distance to permit material such as strips or plates of metal 21, to pass between said ad acent edges of the members 19 and 20.

In the portions A and B of the brackets are elongated slots 22, illustrated in Fig. 1. The members 19 and 20 are adjustably secured to the brackets by means of bolts or screws 23, extended through the slots 22 and secured to the members 19 and 20.

In the practical use of my improved guard for rollers, the brackets are installed on the frame adjacent to the rollers, and the cross members 19 and 20 are then secured to the brackets. The cross members 19 and 20 may be adjusted with relation to each other by loosening the screws 23 and ad justin said members 19 and 20 as may be desired, so as to leave a suitable space between them for permitting the free passage of the material 21.

It is well known that in rolling mills and other places where material is passed through a set of rollers the workmen frequently are injured by catching their fingers between the rollers. Where a device such as mine is used, the material 21 can be fed between the members 19 and 20 to the rollers without danger to the workmen.

My brackets are of extremely simple and inexpensive construction, and by very slight modification may be adapted for use with the rollers having a great variety of arrangements.

It should be understood that some changes may be made in the details of the construction of my improved guard for rollers without departing from its essential features and purposes, and it is my intention to cover by this application any such changes as may be included within the scope of the following claim:

I claim as my invention:v

In a device of the class described, the combination of the frame, and rollers mounted thereon adapted to receive material fed between them with a pair of brackets mounted on said frame, each of said brackets having a portion curved inwardly toward the line between said rollers, a pair of transverse guard members mounted on said brackets, having their adjacent edges curved toward the line between said rollers, for guiding Copies of this patent may be chtaiiied for five cents each, by addressing the Commissioner of Patents,

materiaipassed between them, saidtransverse members being spaced apart to permit the passage of material between them, said transverse members being adjustably mounted on said brackets for varying the distance between their adjacent edges to permit the passage between them of materials 20 of difierent thicknesses.
